Identifying Distinct Prognostic And Predictive Contributions Of Tumor Epithelium Versus Tumor Microenvironment In Colorectal Cancer, Mingli Yang, Moh'd Khushman, Et Al.

2020-Current year OA Pubs

BACKGROUND: Accumulating evidence has suggested that cancer progression and therapeutic response depend on both tumor epithelium (EPI) and tumor microenvironment (TME). However, the dependency of clinical outcomes on the tumor EPI vs. the TME has neither been clearly defined nor quantified.

METHODS: We classified 2373 colorectal cancer (CRC) tumors into the consensus molecular subtypes (CMS1-4) and generated the 10-gene TME

RESULTS: The TME

CONCLUSIONS: Here we identified a pair of new, distinct 10-gene signatures (the EPI

Comprehensive Cross-Sectional And Longitudinal Comparisons Of Plasma Glial Fibrillary Acidic Protein And Neurofilament Light Across Ftd Spectrum Disorders, Udit Sheth, Nupur Ghoshal, Et Al.

2020-Current year OA Pubs

BACKGROUND: Therapeutic development for frontotemporal dementia (FTD) is hindered by the lack of biomarkers that inform susceptibility/risk, prognosis, and the underlying causative pathology. Blood glial fibrillary acidic protein (GFAP) has garnered attention as a FTD biomarker. However, investigations of GFAP in FTD have been hampered by symptomatic and histopathologic heterogeneity and small cohort sizes contributing to inconsistent findings. Therefore, we evaluated plasma GFAP as a FTD biomarker and compared its performance to that of neurofilament light (NfL) protein, a leading FTD biomarker.

METHODS: We availed ARTFL LEFFTDS Longitudinal Frontotemporal Lobar Degeneration (ALLFTD) study resources to conduct a comprehensive cross-sectional and …

Diarrhea is the predominant symptom of acute gastroenteritis resulting from enteric infections and a leading cause of death in infants and young children. However, the role of the host response in diarrhea pathogenesis is unclear. Using rotavirus and neonatal mice as a model, we found that oral inoculation of UV-inactivated replication-defective rotavirus consistently induced watery diarrhea by robust activation of cytosolic double-stranded RNA sensing pathways and type III interferon (IFN-λ) secretion. Diarrhea was significantly diminished in mice lacking the IFN-λ receptor. Mechanistically, IFN-λ signaling downregulates the expression of Dra, a chloride and bicarbonate exchanger, which contributes to reduced water absorption. …

Tracking And Mitigating Imprint Erasure During Induction Of Naive Human Pluripotency At Single-Cell Resolution, Laura A Fischer, Brittany Meyer, Monica Reyes, Joseph E Zemke, Jessica K Harrison, Kyoung-Mi Park, Ting Wang, Harald Jüppner, Sabine Dietmann, Thorold W Theunissen

2020-Current year OA Pubs

Naive human pluripotent stem cells (hPSCs) model the pre-implantation epiblast. However, parent-specific epigenetic marks (imprints) are eroded in naive hPSCs, which represents an important deviation from the epiblast in vivo. To track the dynamics of imprint erasure during naive resetting in real time, we established a dual-colored fluorescent reporter at both alleles of the imprinted SNRPN locus. During primed-to-naive resetting, SNRPN expression becomes biallelic in most naive cells, and biallelic SNRPN expression is irreversible upon re-priming. We utilized this live-cell reporter to evaluate chemical and genetic strategies to minimize imprint erasure. Decreasing the level of MEK/ERK inhibition or overexpressing the …

Treatment Patterns And Outcomes In Follicular Lymphoma With Pod24: An Analysis From The Leo Consortium, Jonathan R Day, Brad S Kahl, Et Al.

2020-Current year OA Pubs

Progression of disease within 24 months of initial immunochemotherapy (POD24) is a negative prognostic factor for patients with follicular lymphoma (FL). There is no standard treatment after POD24. Assembling an academic-based cohort from the Lymphoma Epidemiology of Outcomes Consortium for Real World Evidence, we evaluated patterns of care and outcomes for 220 patients with FL with POD24 and retained FL histology. Therapy after POD24 was heterogeneous, with no treatment category accounting for >25% of the total. Among patients initially treated with bendamustine-rituximab, rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone (R-CHOP) was the predominant second-line choice (48%). Among patients initially treated with R-CHOP, …

Recessive Genetic Contribution To Congenital Heart Disease In 5,424 Probands, Weilai Dong, Sheng Chih Jin, Et Al.

2020-Current year OA Pubs

Variants with large effect contribute to congenital heart disease (CHD). To date, recessive genotypes (RGs) have commonly been implicated through anecdotal ascertainment of consanguineous families and candidate gene-based analysis; the recessive contribution to the broad range of CHD phenotypes has been limited. We analyzed whole exome sequences of 5,424 CHD probands. Rare damaging RGs were estimated to contribute to at least 2.2% of CHD, with greater enrichment among laterality phenotypes (5.4%) versus other subsets (1.4%). Among 108 curated human recessive CHD genes, there were 66 RGs, with 54 in 11 genes with >1 RG, 12 genes with 1 RG, and …

Structural Basis For Dimerization And Activation Of Uvrd-Family Helicases, Ankita Chadda, Binh Nguyen, Timothy M Lohman, Eric A Galburt

2020-Current year OA Pubs

UvrD-family helicases are superfamily 1A motor proteins that function during DNA replication, recombination, repair, and transcription. UvrD family monomers translocate along single-stranded (ss) DNA but need to be activated by dimerization to unwind DNA in the absence of force or accessory factors. However, prior structural studies have only revealed monomeric complexes. Here, we report the first structures of a dimeric UvrD-family helicase,

Myelin transcription factor 1 like (MYT1L) is a neuronal transcription factor highly expressed in the developing and adult brain, and, while pathogenic MYT1L mutations cause neurodevelopmental disorders, these have not been characterized in human models of neurodevelopment. Here, we modeled the consequences of pathogenic MYT1L mutation using human stem cell-derived cortical neurons, demonstrating that MYT1L mutation alters the differentiation trajectory, increasing neuronal gene expression, morphological complexity, and synapse production. We also examined consequences of MYT1L mutation in mature cortical interneurons, identifying hallmarks of impaired neuronal identity and maturation and correspondingly altered channel expression and electrophysiological properties. Finally, by defining MYT1L …

Nad+ Prevents Chronic Kidney Disease By Activating Renal Tubular Metabolism, Bryce A. Jones, Sanjay Jain, Et Al.

2020-Current year OA Pubs

Chronic kidney disease (CKD) is associated with renal metabolic disturbances, including impaired fatty acid oxidation (FAO). Nicotinamide adenine dinucleotide (NAD+) is a small molecule that participates in hundreds of metabolism-related reactions. NAD+ levels are decreased in CKD, and NAD+ supplementation is protective. However, both the mechanism of how NAD+ supplementation protects from CKD, as well as the cell types involved, are poorly understood. Using a mouse model of Alport syndrome, we show that nicotinamide riboside (NR), an NAD+ precursor, stimulated renal PPARα signaling and restored FAO in the proximal tubules, thereby protecting from CKD in both sexes. Bulk RNA-sequencing showed …

High-grade serous ovarian cancer (HGSOC) is the most prevalent and aggressive histological subtype of ovarian cancer and often presents with metastatic disease. The drivers of metastasis in HGSOC remain enigmatic. APOBEC3A (A3A), an enzyme that generates mutations across various cancers, has been proposed as a mediator of tumor heterogeneity and disease progression. However, the role of A3A in HGSOC has not been explored. We observed an association between high levels of APOBEC3-mediated mutagenesis and poor overall survival in primary HGSOC. We experimentally addressed this correlation by modeling A3A expression in HGSOC, and this resulted in increased metastatic behavior of HGSOC …

INTRODUCTION: Electroconvulsive therapy (ECT) is a highly effective treatment for refractory depression, but it may also cause cognitive side effects. Despite decades of use, the mechanisms by which ECT exerts both its antidepressant and cognitive effects are still poorly understood, with the latter substantially limiting referral and adherence to therapy. ECT induces changes in correlated neural activity-functional connectivity-across various brain networks, which may underlie both its clinical efficacy and associated cognitive side effects. Electroencephalography (EEG) could address these knowledge gaps by identifying biomarkers that predict therapeutic outcomes or cognitive side effects. Such developments could ultimately improve patient selection and adherence. …

Preterm birth is detrimental to the well-being of both the mother and the newborn. During normal gestation, the myometrium is maintained in a quiescent state by progesterone. As a steroid hormone, progesterone is thought to modify uterine and placental morphology by altering gene expression, but another direct mode of action has long been suspected. Here, we reveal the nongenomic molecular mechanism of progesterone as the activation of human and murine inwardly rectifying potassium channel Kir7.1, which is expressed in myometrium and placental pericytes during late gestation. Kir7.1 is also activated by selective steroids, including those used to prevent premature labor, …
